Question

如何使上次填充详细信息字段呈现选中的相应储罐的最新liters和date 储罐。例如如果我选择 Tank A ，我会看到表单上最后一次填充date和liters中的数量的自动填充。

我有两个课程fleet_fuel_tank和fleet_tank_log_fuel

如何设置默认值

如果您使用的是旧api ，则可以使用_defaults词典设置默认值：

def _get_default_notes(self, cr, uid, context=None):
    return 'Test note'

# [...]

_defaults = {
    'location': 'Far away',
    'notes': _get_default_notes,
}

尝试使用新api ，因为它会更容易。然后你应该填写这样的默认值：

class FleetFuelTank(models.Model):    
    liter = fields.Char(
        string='Liters',
        default=lambda self: self._get_default_liter(),
    )

    @api.model
    def _get_default_liter(self):
        return 4.5

如何触发onchange方法

如果要动态修改数据，可以使用onchange方法。我在这里向你展示一些例子：

旧API ：

<field name="product_uom_qty" on_change="onchange_quantity(product_id)"/>

def onchange_quantity(self, cr, uid, ids, product_id):

    result = {
        'product_uos_qty': 0.00
    }

    # [...]

    return {'value': result }

新API（xml视图中没有任何内容）：

@api.one
@api.onchange('tank_id')
def onchange_tank(self):
    self.name = 'changes what you want to do'
